MINER, INC, OF CHICAGO, ILLINOIS, A.CORPORATION OF DELAWARE CAR CONSTRUCTION Application filed. January 24,1829, Serial No. 334,693.

This invention relates to improvements in car construction.

One object of the invention is to provide a combined locking and centerpin arrangement for railway car bolsters, of rugged design, which may bereadily applied and effectively locked against accidental re moval,including a pair of locking elements having headed portions at oppositeends, having shouldered engagement with the bolsters, and a centralfiller member for holding said elements separated, said filler memberhaving means at the opposite ends thereof having shouldered engagementwith the elements to lock the same together, said means at both ends ofthe filler member being of such a cross section that when the filler isin oneposition it will pass freely between said elements and when it isturned to another position passage of said means between said elementsis prevented.

A further object of the invention is to provide a center pin arrangementof the character indicated in the preceding paragraph, wherein means isprovided for looking the filler member and the elements against relativerotation in their completely assembled condition.

Another object of the invention is to provide a combined locking andcenter pin arrangement for connecting the body and truck bolsters of arailway car having aligned center pin receiving openings and retainingshoulders adjacent said openings, including a center pin comprising apair of outer members and a filler, said outer members each havinglaterally projecting exterior flanges at opposite ends cooperatingrespectively with the shoulders of the body and truck bolsters, theflanges at corre sponding ends of said members together defining headportions of the pin, the filler member maintaining the outer membersseparated to hold the flanges thereof in overlapping relation with theretaining shoulders of the bolsters, the filler member being providedwith retaining means at opposite ends thereof, engageable with theopposite ends of said outer members to lock the parts together, theretaining Renewed December 5, 1929.

means at both ends of said filler member comprising pairs of lugs which,when registered with the opening between said outer members, will passfreely therebetween and when displaced angularly by rotation of saidfiller member will overlap the corresponding ends of said outer members.

A still further object of the invention is to provide a combined lockingand center pin arrangement of the character indicated in the precedingparagraph, wherein the center pin receiving openings of the bolsters areslotted at opposite sides to accommodate portions of the flanges of theouter members, thus permitting the employment of flange members ofrelatively large size and great strength, thus adding greatly to theruggedness of the center pin member.

Other and further objects of the invention will more clearly appear fromthe description and claims hereinafter following.

In the drawing, forming a part of this specification, Figure 1 is a topplan View of a portion of a body bolster of a railway car, illustratingmy improvements in connection therewith. Figure 2 is a verticalsectional view, corresponding substantially to the line 22 of Figural.Figure 3 is a horizontal sectional View, corresponding substantially tothe line 33 of Figure 2. And Fi ure l is a detailed perspective view ofa retaining member employed in connection with my improved center pinconstruction.

In said drawing, the body bolster of the car is designated by and thecooperating truck bolster by 11. The bolsters proper may be of anysuitable construction and, as shown, the body bolster is provided withthe usual top and bottom webs connected by a tubular section 12. At thebottom, the bolster 10 is provided with the usual hearing projection 13which is of substantially spherical form and is seated in a cooperatingbearing plate 14 which is mounted on top of the truck bolster 11.

The truck bolster 11 is also provided with the usual top and bottom webswhich are connected by transverse vertical walls defining a pocket 15.

In carrying out my invention, I provide the body bolster with a centerpin receiving opening 16, and the truck bolster and hearing plate 14mounted thereon with openings 17 and 18 in alignment with the opening 16and of the same diameter, also adapted to accommodate the center pinmember. The major portion of the tubular section 12 of the body bolsteris 01' considerably greater diameter than the pin receiving opening 16,thereby providing a pocket to accommodate the upper head member of thecenter pin and an annular shoulder 19 at the bottom of the pocket whichcooperates with the head of the pin.

The vertical walls of the truck bolster are spaced apart a distancegreater than the diameter of the pin receiving opening;v 17 of bolster,thereby providing an annular retaining shoulder 20 adjacent the pin.receiving opening 17 at the upper end of the pocket 15. As will beevident upon reference to Figure 2, the shoulders 19 and 20 of the twobolsters are relatively close together, thereby pern'iitting the use ofa short center pin member.

My improved center pin proper comprises a pair of outer members A-A, acentral filler 0-r spacer B, and a retaining member C.

The members A are of similar design, and together form a substantiallytubular outer section of the pin. Eaah of the members A is oi are shapehorizontal cross section, as most clearly shown in Figures 1 and Atdiametrically opposite sides of the center pin, the sections A arespaced apart, as clear- Ly shown in Figures 1 and 3, to provide verticalpassageways between said members, for a purpose hereinafter described.At the top and bottom ends, each member A is provided with laterallyoutwardly projecting horizontal flanges 21-21 which, when the parts ofthe pin are assembled, cooperate with the annular shoulders of the bodyand truck bolsters to lock the same together.

The flange members 21, at the upper ends of the members A, form asubstantially complete head member at the top of the pin.

he flanges 21, at the bottom ends of the members A, form a similar headmember. The portions of the members A, between the heads 21, define theshank of the center pin and present exterior cylindrical surfaces whichsubstantially fit the walls of the center pin receiving openings 16, 17and 18. The center in is provided with a central bore adapte toaccommodate the filler member B, the opposed inner wall portions of themembers A being recessed, as indicated at 2222, to accommodatediametrically opposite sides of the shank portion of the member B. Asmost clearly shown in Figure 1, the flange members 21 of each member Aare (o-extensive with the main body portions of said members, therebyproviding the center pin with head portions of relatively heavyconstruction.

The filler member B comprises a cylindrical shank portion 23 which fitsbetween the members A and has diametrically oppw site side portionsseated within the openings 22 of said members. At the bottom end, theshank 23 is provided with an enlarged portion forming a head member 24;.The enlargement 24 comprises a pair of lugs at diametrically oppositesides of the shank, which engage the bottom ends of the members A. Atthe upper end, the shank 2 of the member B also provided with anenlargement 25 forming an upper head portion. The enlargement 25comprises a pair of lugs disposed at. diametrically opposite sides ofthe member B and in vertical akignment with the lugs of the head 24. Thelugs of both heads are of such a width as to pass lock the members Atogether and prevent relative movement of the members A and B withrespect to each other in an endwise direction. As shown, the heads 2*and 25 closely fit the members A, thereby reinforcing the flanges 21.When the filler member B is removed from between the members A, thelatter may be displaced inwardly toward each other, thereby collapsingor contracting the pin so as to facilitate application and removatthereof.

The walls of the center pin receiving openings 16, 17 and .18 arerecessed at diametrically opposite sides, as indicated by 2626, topresent vertical, guide slots adapted to accommodate the innerextremities of the flanges 21 at opposite sides of each of the members Awhen the pin is collapsed or contracted. The of the pin are soproportioned that the members A may be successively inserted, each.member being oi? such a size that the outer edges of the flanges 21 atopposite ends thereof will, clear the wall portions of the center pinreceiving openings of the bolsters and the opposite inner end edges ofeach of said thrnges will pass thron h the openings 26, the curved endedges oi these flanges being preferably concentric with the curved outerfaces of the shank portions of the members A.

The retaining member C is in. the form of a U-shaped clip having spacedarms 27%? and a transverse connecting portion 28 at the upper endthereof. \Vhen the parts are assembled, the member C has the arms 24'Ill) thereof disposed on opposite sides of the shank oi the, fillermember 13 within the guideways or openings between the members A.

res 2 and i the arms- 2-7 poi ions the arms 27 are rounded on theirouter sides, as inui dat 3.0-30, said rounded portions lying insubstantially the seine "ndrical surface. as the outer surfaces C1; themembers A. The upper por tiens of the arms 27 arelaterally enlarged, asindicated t 3-13l, the enlarged portions being 0. such a length that thebott m portio thereof are seated the recesses 26 of the side walls ofthe pin receiving opening 16; As be erident, the arms 27 of theretaining member G being disposed between the members A will be held arotation with respect to the same, and the transverse upper section 28being seated inthe pocket 29. of the id. or member B willI hold the latcgainst rotation and all the parts will thus belocked together relativerote.- tion. about the axis of the pin. It is further pointed out thatby e1- .gement oi the lower a end portions of the enlargements 33. with:

will.

they 1 co. 26., the entire center pin stuc- "t I: F".1 l 17 l we v m -n1 6 tie vii 3e iocier a ainst rkioublvn m n respect to the bolster 10-,The inner edges oi; the arms 27 are also rounded oii so as to the oppossides oi, the cy Lndrical shank portion 2 the filler member B. In. orderfacilitate the removal of the reaming member C, the same is pro idedWith an upstanding central lug portion 32. having opening 33 withinwhich a removing tool may be engaged.

in applying the center pin to the bolsters 10 and 11, one of the membersA is first inserted either through the body or truck bolster by passingthe flange portion 21 at the corresponding end: of the in er A tl *oughthe pin receiving openings and bringing the flanges at the opposite endsthereof into cooperative relation with the corresponding annularshoulders of the two bolsters. This member is then displaced laterallyoutwardly to overlap the flanges with the shoulders and bring the shankinto con tact with the corresponding side wall portions of the centerpin openings. Suflicient clearance is thus. provided to permit insertionof the other member A. The latter is then, inserted in a. similar mannerand displaced. laterally outwardly to engage the flanges thereof withthe retaining shoulders of the bolsters. \Vhen the members A have beenthus assembled with they bolsters and spread apart, sufficient clearanceis provided between the same to accommodate the filler member B. Thef'ller member B is then inserted between the inen'ibers A. by passingthe upwardly through the pocket or the bolster or downwardly through theof the body bolster. At this time, the lugs forming the h ads 24 and #5are so disposed as to register with the pessageways etween the membersA. When the filler has been hilly inserted so that the heads 2% and 25are disposed respectively below and above the corresp nd'ing ends of themembers A, tl e filler member is given :1 quarter turn so as to disposethe lugs forming the heads and 25 shown in Figures 1 and'2. When theheads are thus positioned, the parts A and B. are locked againstrelative displacement in endwise direction and the members A are held intheir outermost position. with the flanges thereof overle ping theshoulders of the body and truck bolsters. The retaining member C is a;plied by the same through the pocket of the body bolster end engagingthe arms 27 thereof within the passageweys di etrically oppositesides ofthe 1, between the members AK.

The retaining element is passed downwardly until the transverse section28 ther of is seated within the pocket 29 of the head 25.. Ashereinbefore pointed out, all i' the parts of the pin are thusloekerelative rotation. lVhen theret. ber has been fully applied, enla Si orthe arms will engage within the recesses.1?, es hereinbetore pointedout, there by preventing rotation of the center pin with respect to thebody bolster. Although the center pin has been described and showr aslocked he body bolster, it will be e" oer-1t that my invention is notlimited. to th s ecise construction and that the enlargeng member may beomitted, thereby allowing relative rotation of the center structure asva unit with respectto both bolsters. lVith the enlargements 31 omitted,the arms 27 will be looked between the members A. and the retainingmember will be locked to the: filler B by the transverse section 28,thus interlocking all bAMu of th parts of the pin against relativerotamen.

so as to contract or collapse the head portions of the pin formed by theflanges 21 thereof and permit withdrawal of the displaced member. Afterremoval of said member, the other member A is displaced laterallyinwardly to register the flanges thereof with the openings and guidcwaysso as to permit withdrawal oi? the same.
